Good morning . Mrs.Smith .   Good morning ! Can you help me , please ? I'm looking for some books for my mother .   Well , what kind of books does she like ?   She's very fond of detective stories ?   I see . Has she read any detective stories ?   Oh , yes !   Do you know if she's read this one ?   I'm not sure , but she probably won't remember if she has ! She's very forgetful !   Ah ! She has a bad memory . How old is she ?   She's eighty-seven .   I suggest you take this book . It's very exciting .   Thank you . That's a good idea.she likes exciting books . Can you suggest another one ?
